6 Claims. 1

The present invention relates to a gun sight, particularly a rear sight for attachment to the receiver in which the rearward end of the gun barrel is secured. An object of the invention is to provide a rear sight construction wherein the sight member may be formed of a single piece of spring metal, and is adapted to be interlockingly attached to the receiver through cooperative engagement with the inner surface thereof, to the end that the sight member may be firmly and accurately secured and its exposed part will present a neat, smooth and clean appearance.

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In the drawings:

Fig. 1 is a side elevation of a porton of the receiver with the rear sight, according to the illustrated exemplary embodiment of the invention, attached thereto.

Fig. 2 is a plan view thereof.

Fig. 3 is a vertical transverse sectional view, taken along the line 33 of Fig. 1.

Fig. 4 is a vertical transverse view, taken along the line 4-4 of Fig. 1.

Fig. 5 is a side elevation of the sight member detached from the receiver.

Fig. 6 is a bottom plan view thereof.

Fig. 8 is a front end elevation of the sight member.

Fig. 9 is a longitudinal vertical sectional view, showing the sight member assembled with the receiver, and with the sight elevating wedge member removed, the dot-and-dash lines indicating the manner of engaging the sight member with the receiver and also showing the unbent relation of the retaining lug of the receiver prior to securing of the sight member.

Similar reference characters indicate corresponding parts throughout the several figures in the drawings.

Referring to the drawings, the receiver I0 is formed of sheet metal and is of generally inverted U-shape in cross-section, the forward portion of its upper side being semi-cylindrical to receive the rearward end of the gun barrel II, which is secured therein, while the rearward portion of its upper side recedes in a downwardly and rearwardly inclined curve. In the upper side of the receiver, at a point rearwardly of its semi-cylindrical forward portion, there is provided a transversely disposed slot I2 of rectangular outline and in rearwardly spaced relation thereto there is provided a rectangular opening I3, the metal cut from this opening being bent downwardly at the rearward transverse edge of the opening to provide a securing lug I4 for the sight member. This lug, before assembly and securing of the sight member, stands downwardly substantially at right angles to the upper side of the receiver, as shown by the dot-and-dash lines in Fig. 9, and is adapted to be bent upwardly from this position to secure the sight member, as will presently more fully appear.

The sight member is formed of spring metal and comprises a spring arm portion I5 provided at its rearward end with an upwardly bent leaf I6 having a sight opening I! therein. A longitudinal slot I8 is provided in the arm I5, its rearward end wall being disposed within the bend at the base of the leaf I6 to provide a tooth formation I9 for the notched elevating wedge member 2|] engaged and. positioned within the slot for longitudinal adjustment.

The arm portion I5 is connected at its forward end by a spring bow portion 2| to a base portion 22 which extends longitudinally rearwardly beneath the arm portion I5, being upwardly offset adjacent the spring bow portion 2|, as at 23, to provide a seating shoulder to engage the outer surface of the receiver. This seating shoulder is transversely bowed, so that its under surface conforms to the outer curved surface of the receiver at the forward edge of the slot' I2, while the downwardly offset reach of the base is transversely bowed, so that its upper surface conforms to the inner curved surface of the receiver between the slot I2 and the opening I3. The shoulder 23 is connected to the base portion 22 by a reversely curved neck portion 24, adapted in the assembled position of the sight member to engage within the slot I2, this neck portion being provided centrally with a rearwardly projecting tongue 25 upwardly offset from the cut 26 in the base by which it is formed, so that in the assembled position of the sight member it will engage within the slot I2 in flush relation with the upper side of the receiver. At the rearward end of the base portion 22 there is provided a tongue 21 formed by a pair of parallel cuts 2828 and bent into upwardly ofiset relation to the base, the space in the end of the base between the cuts 28 con- 2,4oasov 3 stituting. a positioning recess for engagement by the lug I4.

In order to assemble the sight member with the receiver, the base portion 22 is inserted downwardly through the slot I2, as shown by the dot-and-dash lines in Fig. 9, and is forced downwardly and rearwardly, with the spring arm portion l5 yielding upwardly through its engagement with the upper surface of the receiver, to the point where the neck portion 24 enters the slot. At this point the base portion is free to swing upwardly into engagement with the inner surface of the receiver, while the seating shoulder 23 swings downwardly into engage ment with the outer surface of the receiver adjacent the forward edge of the slot l2, as shown by the full lines in Fig. 9. In this position the tongue 25 is engaged in the slot I2 in flush relation with the upper surface of the receiver, with its rearwardly projecting end engaged with the rearward wall of the slot 12 to prevent rearward displacement of the sight member, and the tongue 21 is engaged in the opening l3, the downwardly standing securing lug I4 being engaged in the recess between the cuts 28-28, as shown by the dot-and-dash lines in Fig. 9. Thereupon the lug I4 is bent forwardly beneath the tongue 21 to thus secure the base of the sight member within the receiver.

Following the assembly of the sight member, the arm I5 is sprung upwardly from its position as shown in Fig. 9, and the elevating wedge member is engaged within the slot l8, as shown in Fig. 1, with the tooth formation 19 engaged in one of the notches thereof. By longitudinal adjustment of the wedge member the elevation of the sight opening I! may be adjusted as desired.

The form of the invention illustrated in the drawing and described herein is typical and illustrative only, and it is evident that the in vention is capable of embodiments in other forms, all falling within the scope of the appended claims, which are to be broadly construed.
